FMD-97 lists only shorted, failed BVR and loose particle. Also, one manufacturer rep indicated that shorted and degraded types are the most common, with no info on other types of failures. Thanks!

Message: Why is research that has been conducted under the funding of the US government for sale? That research has been paid by US tax payers and it should be freely available to ALL US tax payers, period. Why do you sale these reports? Why don't we have access to that information for free? Thanks HM

Posted by: Donato Tartaglia Date posted: Wed Nov 19 12:48:11 US/Eastern 2003 Subject: Library maintenance Message: I need to delete my component library because now i have a new import file with the SAME components ( 1700 part numbers) that are now in the library but with a new field ( the component description ). When I try to import from this file (it is a text file) I receive a message ( zero components imported because there were 1700 duplicated records). Probably one field ( Industry Part Number ?? ) is recognised like a primary key and it’s impossible to duplicate. So, how can I delete 1700 components ( no multiple selection is possible in the component library interface) to perform a new, complete, import. Thank you

I need it for a reverse osmosis and a demineralizer cartridge for a residential system. And I need the MTBF for a conductivity measurement in water. Have anybody an idea for a fuel cell ( PEM ), or for membranes? Thanks for helping! Best regards from Germany. David Wegener
